Moreover, I have compiled above snipped using cppcoro library with clang 9.0.0 on wandbox. Boost Iterator Facade Design Pattern in C++ . If you have gone through my Facade Design Pattern article, you know that the first word in the above title i.e. Facade pronounces as `fa;sa;d`.

Already with range-v3 you can use the following code to define a range of all the integers and apply a filter to them: Re-write IFN_CO_YIELD, deferred to post-LTO (this was expected to produce the best opportunities for optimisation, but it's a CHECK-ME to compare pre and post). This rewrites the actor function so that the suspend/resume paths are distinct from the destruction ones, allowing the ME optimiser to inline the functionality separately and DCE the unused portions. `yield` keyword to become `co_yield` in VS 2017 EricMittelette January 27, 2017 Jan 27, 2017 01/27/17 Coroutines—formerly known as “C++ resumable functions”—are one of the Technical Specifications (TS) that we have implemented in the Visual C++ compiler. В этой статье мы подробно разберем понятие сопрограмм (coroutines), их классификацию, детально рассмотрим реализацию, допущения и компромиссы, предлагаемые новым стандартом C++20. Clang + llvm coroutines allows you to take this code: generator range(int from, int to) { for(int i = from; i < to; ++n) co_yield i; } int main() { int sum = 0; for (auto v: range(1,100)) sum += v; return sum; } And translate it down to this: define i32 @main() #5 { entry: This generator satisfies the co_yield interface of a coroutine. A very rough view is that the call co_yield is replaced by the compiler calling yield_value. So promise_type_base serves as a container for the value coming from the coroutine into our normal code.

So in this sense, to “resolve foo as a DR” connotes “to apply the same fix uniformly across all language modes.” EBO, EBCO Coroutines Yehezkel Bernat yehezkelshb@gmail.com Core C++ Meetup, Sep. 2018 layout: true
